Combine lime, sugar, and slices from 2 kiwi fruit in a cocktail shaker. Using the handle of a wooden spoon, smash fruit to extract juices. Add about 2 cups ice and the cachaça. Shake to blend well, then divide contents, including ice, between 2 glasses. Garnish with kiwi.
*Cachaça is a Brazilian sugarcane liquor. Find it at well-stocked liquor stores.
